UNITED STATES JOSEPH A. FIRSCHING, OF U'IICA, NEW YORK.

KNITTING MACHINE.

Application filed November 15, 1921.

To all whom it may concern:

Be it known that I, JOSEPH A. F msomno, of Utica, in the county of Oneida, in the State of New York, have invented new and useful Improvements in Knitting Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in knitting machines, and pertains The application of oil to and by the presser results in considerable waste of oil, and very often in the distribution of oil upon the knitted cloth and thread, and re- The object of my invention is the production of an efiicient and economic means requiring very infrequent attention for applying oil to the needles without danger of the oil being distributed upon the cloth or thread. The efficiency of the hereinafter described is such that-the speed of the machine can be materially in creased without heating the needles or the sresser.

Other objects and advantages relate to the details of construction of the mechanism, all as will more fully appear from the following description, taken in connection with the accompanying drawings, in which 2- Figure 1 is a top plan view of the oiling device.

Figure 2 is a sectional view of the same.

Figure 3 is a side elevation of the same.

The invention as here illustrated, comprises the combination with the needles -1 of the knitting machine, of a rotary absorbent disk -2- of felt or similar suitable material arranged for contact with the needles 1 adapted to be rotated by such a contact when the needles are rotating in the usual manner. This disk 2- applies the oil to the moving needles.

For the purpose of supplying oil to the disk in suitable quantities for application to the needles, various mechanisms and structures may be utilized, that shown be Serial No. 515,204.

ing illustrative of a perhaps preferred construction, so far as my present experience teaches.

The disk -2, as shown, is secured between the members 3 and -4L, the member 3+ being provided with a laterally extending bearing 5 upon which the disk 2 is mounted, and with a reduced threaded end portion -6, upon which the internally threaded member -4 is mounted, so that upon relative movement of the members 3 and 4- in one directionfthe disk 2 is gripped tightly between said members so that the feed of oil thereto, as hereinafter described, can be regulated, if desired, by compression of the disk. The member -4 is provided with an annular groove or recess -7- constituting an oil well for receiving an retaining the oil and feeding the oil thru a series of openings or perforations -8 in the bottom wall of said recess to the absorbent disk or pad 2. This structure, consisting of the absorbent disk 2 and the supporting and retaining member 4 the latter of which is adapted to receive, retain and feed the oil through the disk -2, is mounted in a rotatable manner upon a stud or journal 9, provided with a head 10 at its upper end formed with an oil receiving space or recess -11- leading to a lateral conduit 12- adapted to supply oil from said recess to the interior of the bearing 5. This post may be supported in any suitable manner from the frame of the machine, and for this purpose is shown as carried by an arm 13- having an opening through which the stud 9 extends and to which it may be secured in various relative positions by means of adjusting screw 14.

The oiling structure proper, consisting of the disk 2- and clamping members 3 and l, is loosely and rotatably mounted upon the stud 9- so that frictional contact with the rotating needles 1 will cause similar rotation of the disk --2 to adequately supply oil to the needles without material friction or strain upon any of the parts.

It is found in actual practice that it is only necessary to apply oil to the annular groove or wall 7 about once a day at infrequent intervals, and that this method of supplying oil to the needles saves a considerable percentage of the amount of oil ordinarily used, and further, the cloth does construction or arrangement of the same, as

various changes may be made therein without' departing fromthe' invention, as set forth-in the appended claims. I claim:

1. An oiling tlevice-for rotary knittingmachines comprising a felt disk having a portion of' its periphery in the path of 'movement of the needles, and means foa rotatably supportingsaid' disk to permit its vfree rotation by contact With the needles.

2. An oiling device for rotary knitting machines comprising an oil-containing retaming disk having a portion of 1ts periph cry 1n-'the=path of'm'ovement of the needles of the machine, means for rotatablysupporting said disk to permit its free 'rotation with the needles, a receptacle above said disk, and means of communication between the receptacle and the disk for supplyii 1 oil to the latter from the former. V

3. An oiling device for rotary knitting machines comprisinga felt disk having a portion of its periphery in the path of movement of the 11eedles,*means for rotatably.

In Witness whereof I have hereunto set H. OHAsE', M. R; CooKE.
